Vcore Reading vs Vcore Configuration

If I set my Vcore in my bios to 1.4, and my software programs such as CPUz and Everest read 1.35 what is the actually voltage? It seems that my vcore is always lower then what I set it to in bios...
 
That voltage drop for bios to Windows to full load happens to most users that haven't volt modded their motherboards. Everest is the most accurate at reporting voltage so stick with that.

What you set your cpu voltage to in the bios doesn't mean too much. The important number is how much voltage is your cpu getting when at full load running Orthos and Everest will properly tell you that.
 
I have similar specs to you.


Asus p5B Deluxe
C2D e6420
Corsair XMMS PC-6400



I'm set at 1.425 Vcore or something in bios. Everest reads 1.36-1.39

NBv is 1.45
FSB Termination.v 1.4


3.2ghz
8x400 fsb
1:1

Oh, and for some reason the bios says PC-4300 which is also odd. Cpuz reads correctly(PC-6400)
I idle at 32c, And one of the core seems a lot cooler then the other. core1 25-28c idle core2 28-32c ... Could my thermal compound not be covering one of the cores to well?
 
With an E6x20 cpu, when you set your memory to run at 1:1 it assumes you are trying to run your computer with some PC-4300 memory which is DDR2-533 which runs at 266 MHz which would be the front side bus if you weren't overclocking.

If CPUz reports that your memory is running at 400 MHz then that means you have it nicely overclocked to DDR2-800 speed. Ignore what the bios says when it's booting up.

Idle temperatures are not important. There seems to be a small margin of error in the sensors at idle so a slight difference in reported temperatures at idle is quite common. Use CoreTemp 0.95 or SpeedFan 4.32.

Run Orthos and you can plot the temperature of both cores over a 13 minute interval using SpeedFan. The cores will likely be +/- 1C, the majority of the time, when at full load.
